' application filed June 6,

To all whom it may concern;

Be it known that l, JOHN P. HORN, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Furniture Attachments, of which the following is a specification.

This invention relates to upholstered furniture, and has for one of its objects to provide an insecticide holder supported in the framework of such devices to prevent insects from attacking the upholstering.

Another object of the invention is to pro- :vide a device of this character which may be applied without material structural change to articles of upholstered furniture of vari ous forms and sizes, and whose presence will not be apparent and does not require any change of form of the furniture. I

Another object of the invention is to provide a device of this character whereby air currents are caused to pass through the insecticide holders by the compression and reaction of the spring supported seat, to carry the emanations from the insecticide substance into contact with the upholstering material every time a person occupies the seat and rises therefrom.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a front elevation of a conventional upholstered arm chair with the seat frame partly in section, and the improved insecticide holder supported therein.-

Fig. 2 is a vertical section on the line 2-2 of Fig. 1.

Fig. 3 is a transverse section on the line 3--3 of Fig. 1.

Fig. 4. is a plan view, and- Fig. 5 is a side elevation, of the insecticide I holder.

chair, in which 1O re resents the seat fr 11 the back frame, an d 12 the arms. mm,

The upholstered seat portion is represented conventionally at 13 and is supported by springs 14, in the usual manner.v

Built into the framework are one or more receptacles for a container for an insecticide compound, and 'fOIjthfi purpose of illustratIOII IS shown formed by partition members 15 spaced from the side and back rails 10 of the seat frame and provided with numerous vent apertures 16.

Suitably supported within each of the re. ceptacles 1s a holder for an insecticide, each holder consisting of'a casing or frame having endmeinbers 17 connected by upper and lower side bars 18 and with the sides and bottom of screen material represented at 19. The top portion of the'holder is formed with an intermediate section 20, and detachable lateral port ons 21, preferably of wood and provided with numerous vent apertures 22.

The detachable portions 21 provide means for the insertion and removal of the insecti cide element which may be of'any suitable substance or material, for instance red cedar chips charged with asuitable formaldehyde.

The weight of a person occupying the seat 13 will depress the latter and force air.

through the apertures in the holder, and then when the occupant of the chair rises, the reaction of the springs 14 will cause the upholstering and its padding to draw fresh air into the holder and cause the charged air in the holder to impregnate the upholstering material and thusprotect it from the attacks of insects.

A suction action is thus produced by the compression and-expansion of the seat structure caused by the occupant sitting and rising, as will be obvious.

The receptacles for the insecticide containers being located entirely within the lines of the frame members, are not visible from the outside and do not therefore detract from the appearance "of the furniture, and do not add materially to the expense or weight.

The improved attachment is simple in construction, can be arranged in any portion of the framework of upholstered furniture, and eflectiv'ely prevent insects from attacking the fabric constituting the upholstering.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the in, a casing adapted to receive an insecticide and having foraminous walls and received in said receptacle.

3. An article of furniture including the seat framing and the spring supported seat, said framing having a receptacle built therein, a casing adapted to receive an insecticide and having 'foraminous walls and received in said receptacle, whereby the depression of the seat will force air through the holder and in contact with the. insecticide therein and the return of the seat to distended position will draw the charged air into contact with the upholstering.

In testimony whereof, I afiix my signature hereto.

JOHN P. HORN.
